Caution: a recent measurement is approaching a regulatory limit
Lead measured at 0.003 mg/L in the most recent sample (caution).
Risk classification follows EPA published MCL / MCLG / HAL values with caution and concern bands reviewed by a clinician. Past resolved violations do not influence this badge. See methodology.
Lead service line inventory
No inventory data on file
We do not yet have this utility's published Lead Service Line Inventory on file. The EPA Lead and Copper Rule Improvements (LCRI) required every community water system to publish one by October 16, 2024 and to identify and replace any lead lines within 10 years. How lead enters drinking water.
Phase 1 coverage focuses on the largest NC utilities. Smaller systems will be added; in the meantime, ask your utility for their inventory or check their Consumer Confidence Report.
Lead and Copper Rule sample data
The most recent measurement per contaminant from EPA's Lead and Copper Rule (LCR) sample table. This is the only per-system sample data EPA publishes in the bulk SDWIS download; values for other regulated contaminants (TTHMs, nitrate, arsenic, etc.) are tracked on this page only when they trigger a violation.
| Contaminant | Most recent | Date | Risk |
|---|---|---|---|
| PB90 | 0.003 mg/L | June 30, 2024 | Caution Lead has no safe level (MCLG=0). LCR action level is 0.015 mg/L for the 90th-percentile sample; the LCRI (Oct 2024) lowers the action level to 0.010 mg/L effective Nov 2027. Caution at any detection above LOD; concern anchored to the future LCRI value (0.010 mg/L) for forward consistency. Learn more about Lead. Source. |
PFAS and emerging contaminants (UCMR 5)
EPA's fifth Unregulated Contaminant Monitoring Rule cycle (2023; 2025) tested every public water system serving over 3,300 people for 29 per- and polyfluoroalkyl substances (PFAS) and lithium. This system was tested 720 times across UCMR 5; 3 of those substances were detected in at least one sample. Most-recent detection per contaminant shown below.
| Contaminant | Most recent detection | Date | Risk |
|---|---|---|---|
| 8.4 ng/L | July 22, 2025 | No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about HFPO-DA. | |
| 4.6 ng/L | July 23, 2025 | No federal limit EPA has not set a federal drinking-water limit for this contaminant. It is among the substances EPA is studying under the Unregulated Contaminant Monitoring Rule (UCMR). See the guide for what the science currently says. Learn more about PFBS. | |
| 0.0153 mg/L | July 23, 2025 | Below regulatory thresholds HAL only; not enforceable. UCMR-monitored. Learn more about lithium. Source. |
Tested but not detected (27 contaminants)
EPA tested for these substances and every sample was below the minimum reporting level. Absence of detection does not mean true zero; it means below the laboratory's quantitation threshold.
Compliance history
EPA-recorded violations against this system over the last 5 years. Health-based violations are when a measured limit was exceeded; monitoring and reporting items are paperwork issues (missed sample dates, late filings) that do not themselves indicate unsafe water.
No health-based violations
No health-based violations on file in the last 5 years. EPA recorded 3 monitoring or reporting items (paperwork) during the same period.

Where to see every contaminant this utility tested for
EPA's bulk SDWIS dataset gives MyTapWater.us per-system measured values for lead and copper, plus violation records for everything else. To see every regulated contaminant this utility tested for in the past year (TTHMs, HAA5, nitrate, arsenic, fluoride, chromium, etc.) with measured values, read the utility's Consumer Confidence Report (CCR).
Every community water system is required by EPA to publish a CCR annually, by July 1, listing every contaminant they sampled, the measured value, the federal limit, and any health-based exceedances. Most utilities post the report online; some mail it with your bill.
How to find THE CAPE MASTER SYSTEM's CCR:
-
Search
"THE CAPE MASTER SYSTEM consumer confidence report"in your browser. The PDF is usually on the utility's own website. - Or check EPA's CCR finder for NC0465199 (some utilities upload theirs to EPA, some do not).
- Or call the utility directly. Their phone number is in the contact section below.
